跨RNC切换的问题，希望使用SPAN OUTUM的大侠指教！

我是个大唐OUTUM路测的新手，又一个问题困扰了我很长时间，今天发帖，希望哪位用 span outum软件的大
侠们帮我解决下，谢谢。
   在资料上说：
1，跨RNC的切换，我们从关键事件上看：Interfreq Hard Handover start.
                                                                          Interfreq Hard Handover success.
                      UU消息上看  ：Radio Bearer channel Reconfiguation(DL-DCCH)
                                                  Radio Bearer channel Reconfiguation complete;

2.在同一个RNC下进行切换：关键事件上看：Interfreq baton Handover start.
                                                                               Interfreq baton Handover success;
                          uu消息上看：physical channel reconfiguation(dl-dcch)
                                                 physical channel reconfiguation complete;
但是在实际的路测中：我发现不完全是这样的。比如说：在同一个RNC下进行切换它显示：
                              关键事件上看：Interfreq Hard Handover start.
                                                         Interfreq Hard Handover success
                               uu消息上看：physical channel reconfiguation(dl-dcch)
                                                       physical channel reconfiguation complete;
                同一个RNC下切换：他还显示：关键事件上看：Interfreq Hard Handover start.
                                                                                                    Interfreq Hard Handover success
                                 
                           uu消息上看：Transport channel reconfiguation(dl-dcch)
                                                   Transport channel reconfiguation complete;
更有甚者：在同一个RNC下进行切换后的信令就和我认为的跨RNC切换的信令是一样的。请大侠帮我细细说下
，我将不胜感激！

期待高手回答！！

RNC内没有启用接力切换吧
